PLOW.

SPECIFICATION forming part of Letters Patent No. 258,115, dated May 16,1882.

Application filed December 5, 1881. (Model.)

To all whom it may concern Be it known that I, ADDISON F. PUREFOY, ofWake Forest, in the county ot' vl/Vake and State of North Carolina, haveinvented a cer tain new and useful Improvement in Flows, whereof thefollowing' specification is a full deg scription.

This invention has for its object to'secure simplicity and lightness,combined with strength, in the construction, and to obtain increasedefliciency in action.

It relates to a special construction of the plow-beam; to the means forpermitting the angular adjustment of the plow proper on the beam; to themeans for securing the coltcr and other attachments to the plow; to animproved subsoiler and barrow attachment to the clevis or means ofcommunicating the draft, and to the general construction of theimplement, the severa-l 'parts being adapted to the beam ot' the specialconstruction before referred io.-

In the present invention the beam is of wrought or rolled metal (iron)plate, bent near the bottom at a right or oblique angle, so as to form atlange on one side, leaving the other plain.

The standard of the plow is secured to the beam by means ofa bolt, onwhich it may turn, and a steady-arm which extends from the standard overor through the beam and down on the opposite side, thus embracing aportion thereof. The top of the said arm moves over a circular areformed on top the beam, or in a curved slot in the body thereof. Thissteadyarm is preferably made in one piece with the pivot-bolt of a bentbar, having both ends threaded for the reception of nuts.

The connection of the plow-standard with the beam by means ofthepivot-boltand steadyarm,while made with veryfew parts, allows the plowto be turned on the pivot-bolt and set at different angles to the beam,so as to run deeper or shallower, and at the same time it makes a verystrong and reliable fastenin o'.

In order to hold the plow in the position to which it is adjusted, atoothed segment, with the teeth on one side, is attached to thestandard, and is combined with a stop-piece formed of bent bar,(iixedatone end and at the other passing througha hole in the heam,) and held inengagement with the teeth of the segment by means oi a nut. By looseningthe nut the stop-piece can be disengaged from the segment and the lattermoved with the plow till the latter is brought to the desired angle, andby tightening it the toothed segmentmvitlrthe plow, is held in place.The segment, also extending along the face of the beam in close contacttherewith, increases the steadiness of the structure and impartsadditionalstrength to the connection between the plow proper and thebeam.

The colter is attached to the plow-standard so as to be adjustable withit. A subsoiler is also combined with the plow, being` arranged toproject under the plowshare. A barrow attachment is also provided, andis fastened in front of the standard, whereby it is brought very closebehind the point of the plow, rendering the implement not only morecompact,r butot' greater efficiency, and the drag, or, more properly,the thrust, is directly the standard, so that the strain upon theconnecting devices is resisted in thebest way.

"The attachments are not only adjustable with the plow, but areadjustable up and down on the standard thereof. rlhe same meanssubstantially are used for securing the colter, subsoiler, and harrow,and they could be used also for securing other attachments.. Theycomprise a bent plate fastened to or made in one piece with theattachment, and provided with a pin which lits into any one ofa seriesof holes in the plow-standard. A double bolt, with a nut on each end,holds the bent plate against the side ofthe standard.

In order that the barrow may be made very light and strong, the body isconstructed of sheet metal (iron) with a iiange turned over at thetop,'in which flange notches are made for the reception ofthe teeth. Theteeth are held below by bolts or clamps, and are provided on the backwith grooves for the reception of the edge of the flange. The teeth areeach thus secured detachably and adjustably to the body ofthe barrow, sothat should one be broken it can be set lower or be replaced readily byanother. This construction is applicable as well to a cultivator as to aharrow, the proper-shaped plow-like teeth being substituted for those ofa barrow.

In connection with the plow and harrowa sustained by e 25ansdepth-regulator is employed to regulate the depth at which they operate.This depthregulator has a grooved shank, by which, in connection withthe bent bar or double bolt t'or securing the colters or otherattachments in place,it is adjnstably retained in position.

In order to regulate the direction in which the draft is applied, so asto throw the plow more or less toward the land side, or to make it rundeeper or shallower, an improved form of clevis is employed. To this endthe clevis, which is detachably connected with plow-beam, is providedwith a toothed cross-bar, which, in connection with a vertical toothedplate on the end ot' the beam, enables the desired adjust ment up anddown and right and left to be secured. The vertical toothed plate isattached to the upright part ofthe beam by means of bolts working inslots, so as to permit to the said plate a limited sliding movementlengthwise ofthe beam. This toothed plate might be called a clevis,butfor clearness ofdistinction the term will be herein restricted to thedetachable part to which the draft is applied. The connection of theclevis with the beam is made by means of a hook in the upright partofthe beam, in which hook the tail end ofthe clevis tits, and wherein itis locked bythe forward movement of the vertical toothed plate.

The" said movement ofthe vertical toothed plate also serves to engagethe teeth thereof with `those of the cross-bar on the clevis and to lockthe latter in the position to which it has been adjusted.

The following description, in connection with the accompanying drawings,which form a'partof this specification, will enable those skilled in theart to which it appertains to make and use the invention.

' Figures l and 2 are views in elevation on opposite sides of a plowprovided with colter, subsoiler, and depth-regulator attachments; Fig.3, a perspective view of the plow proper with barrow attachment; Figs.Land 5, vertical oross-section and horizontal section, respectively,showing the connection oftheplowstandard with the beam and Fig. G, ahorizontal section, showing the means for securing this attachment tothe plow standard. Fig. 7 shows the beam detached; Figs. S and 9, thebody of the barrow andthe teeth, respectively; Fig. 10, a half-harrow;Fig. 11, a cultivator-tooth, to be substituted, if desired, in placeofthe harrow-teeth; Fig. 12, the clevis detached; Fig. 13,the verticaltoothed plate on the end ot' the beam, and Fig. M the bolts and nuts forattaching the said plate to the beam.

j The same letters of reference indicate like parts in all the ignreswherein they occur.

The beam is formed of a wrought or rolled plate ot' iron or othersuitable metal, bent near the bottom at an angle, preferably a rightangle, as shown, so as to form an upright plate, A, With the iiange B atthe bottom. The handles C, connected by a cross-bar, as usual, arebolted ,on opposite sides of the upright plate A.

The standard I) of the plow proper is attached on the plain side oftheplate A, or side opposite from the flange B.

Near the bottom ot' the plate or beam is a pivot-bolt, E, and above thisa clamp or steadyarm, F, bent over the top of the beam at j', andfastened in the standard.

As shown, the pivot-bolt and steady-arm are formed of a single bent baror rod, screwthreaded at both ends, and provided with nuts e. Thepartfof the clamp or steady-arm works over an are, G, cut in the top ofthe beam.

H is asegment bolted to the standard, being, as shown, held by the nutse. 'It is provided with a curved row of lateral-projecting teeth h.

I is thc stop-piece, with one end held on the bolt E andthe other bentand passing through a hole, if, in beam A and engaged by a nut, t. Byloosening the nati' the stop-piece Lean be released from the toothedsegment, and the plow can be turned on'the pivot-bolt E to the desiredangle with respect to the beam, and by again tightening the nut it willbe held in the position by the engagement of the stoppiece I with thetoothed segment. The plow is held steady by the clamp or steady-arm F,embracing a. portion lot' the beam or plate A, and also bythe segment H,bearingagainst the face ot' the said beam or plate.

The colter K, snbsoiler K', and harrow K2 are eachsecured to theplow-standard by a bent plate, 7c, which embraces three sides of thestandard, said plate being fastened to or made in one piece with theattachment, a pin, 7c', that fits into any one ot a series ot' holes,k2, in the plow-standard, and a double boit, k3, with cross-piece andnuts, that hold the bend in plate lo against the standard and the pin kin the hole k2. The shape of the colter and subsoiler may bevmore orless modied; but that deemed most advantageous is represented in thedrawings.

By releasing the bolt 7c3 the attachment colter, subsoiler, or harrowcan be removed. It can be secured in a new position,higher or lower, thepin k being placed in a higher or lower one ot' the holes 7a2.

The body l of the harrow is composed of a wrought cr rolled plate ofiron or other suitable metal, turned over at the top to forma tlange, c.The bent plate 7c is secured in the. rear ot' the body I., and thestructure is stift'- ened by side braces, when deemed necessary. In thetiange l a series ot' notches are formed. The teeth Z2 are secured inthese notches. At their back are grooves Z3,that tit over the edge ofthe flange at the bottom of the notches. Bolts l* embrace the lowerparts ot' the teeth and hold them close against the body of the harrow.The teeth may have any suitable form,wl.iereby theyare adapted tospecial purposes. They may be plain barrow-teeth, as shown in Fig. 9, orthey may be shaped so as to act as cultivators, Fig. 11. When the harrowis secured in place on the plow the bent IOO IIO

25ans 3 attaching-plate extends forward of the stand `ard, and the teethfollow closel behind th point of the plow.

The depth-regulator consists of a shoe, M, andan upright, M. The latteris provided with a series of oblique grooves, m, and is held against thelandside of the plow-standard by the bolt k3, that holds the colter orother attachment in place. The shoe M may be attached to the upright Mby any of the ordinary means for fastening the parts together.

At the forward end ofthe beam is the vertical Vtoothed plate N. It isplaced preferably on the same side of the beam or plate A as the iiangeB, with its lower edge resting on the latter. The bolts a, which hold itin position, pass through slots n,wherebyalimited Inovement is allowedto said plate when the bolts are loosened.

Near the top of the toothed plate N is an angular slot, a2, and in theplate A of the beam is a similar-shaped slot, a5, by which a hook isprovided for the tail of the clevis. Thisclevis consists of a barLbentand twisted, as shown,-

(see Fig. 12,) and a toothed cross-hanf). The bend p' is inserted in theslotsn2 a5, the toothed plateN being at its rearmost position, so thatthe two slots coincide. When the clevis has been inserted the toothedplate N is moved forward, so as to close the opening into the slot,

and at the same time 'cause thc teeth of the vertical plate N to engagewith those of the cross-bar p.

Itwill of course be understood that before advancing the verticaltoothed plate the clevis Lhas been adjusted to the position it is wishedfor it to assume, so that it will be held in that position by theengagement of the teeth. The vertical toot-hed plate is held in theadvanced position by tightening the bolts.

The operation of the improved plow is stifliciently apparent withoutfurther explanation.

It is obvious that modifications could be made in the detailsofconstruction without departing from the spirit of the invention, andthatportions of the invention could be used without the others. Forexample, the means described for securing the colter and other attachments to the plow-standard could be used to secure them to asupplementary standard in front of or behind the plow.

Having thus described my said invention and the manner in which the sameis or may be carried into effect, what I claim, and desire to secure byLetters Patent, is-
